Omega-3 deficiency: 7 signals many people do not recognise

Omega-3 fatty acids are essential for the body and play an important role in various processes. Yet many people do not get sufficient omega-3 through their diet, without being aware of it.

An omega-3 deficiency can manifest in different ways, but the signals are often not immediately recognised. In this article, we discuss 7 common signs that may indicate a low omega-3 intake.

What is omega-3 and why does it matter?

Omega-3 is a group of essential fatty acids, including EPA and DHA. These fatty acids are relevant to, among other things:

• cell structure
• brain composition
• the heart
• the eyes

Because the body cannot produce omega-3 itself, it must be obtained through food or supplements.

How does an omega-3 deficiency develop?

An omega-3 deficiency usually develops through:

• a low intake of oily fish
• a diet high in omega-6 fatty acids
• limited absorption of EPA and DHA

In modern dietary patterns, the balance between omega-3 and omega-6 is often disrupted, which can contribute to a relative deficiency.

7 signals of a possible omega-3 deficiency

The following signals may indicate a low omega-3 intake. It is important to note that these complaints can have multiple causes.

1. Dry skin

Omega-3 plays a role in the structure of the skin. A low intake may be associated with:

• dry or tight-feeling skin
• reduced suppleness
• a dull appearance

2. Fatigue

A low energy level can be related to various factors, including diet. Omega-3 is involved in various bodily processes and is a component of a balanced diet.

3. Reduced concentration

DHA is an important structural component of the brain. Research into its role in cognitive function is ongoing, with studies looking at areas such as:

• concentration
• mental sharpness
• focus

4. Sensitive or dry eyes

DHA is a structural component of the retina. A low omega-3 intake may be associated with:

• dry eyes
• irritation
• eye fatigue

5. Stiff joints

Omega-3 fatty acids are involved in various processes in the body, including those related to joints.

A low intake may be associated with:

• a feeling of stiffness
• less fluid movement

6. Skin concerns

In addition to dry skin, a low omega-3 intake may also be associated with:

• restless skin
• redness
• reduced skin condition

7. Dietary imbalance

While not a direct symptom, a diet low in omega-3 and high in processed foods may indicate an increased risk of insufficient intake.

How can you address an omega-3 deficiency?

Addressing an omega-3 deficiency starts with diet. Rich sources include:

• oily fish such as salmon and mackerel
• flaxseed and walnuts (for ALA)

Because plant-based sources are converted less efficiently into EPA and DHA, many people opt for a supplement.

Omega-3 as a supplement

A supplement can help increase the daily intake of omega-3. When choosing one, it is important to pay attention to:

• sufficient EPA and DHA
• high quality and purity
• good bioavailability

Consistent use plays an important role in building up adequate intake over time.

When will you notice a difference?

Building up omega-3 intake is a process that takes time. Depending on the situation, changes may gradually become noticeable after several weeks.

A balanced lifestyle with healthy nutrition and sufficient exercise remains essential throughout.

Conclusion

Insufficient omega-3 intake is more common than many people think and can be associated with various signals, such as dry skin, fatigue, and reduced concentration.

By paying conscious attention to diet and, where necessary, using a supplement, omega-3 intake can be improved as part of a balanced lifestyle.
